My invention relates to improvements in winter front. cover installations for automobile radiators and the like and aims generally to improve existing installations.

In the drawing which illustrates a preferred form of my invention 7 Fig. 1 is a front view of a complete installation showing the use of my novel fasteners;

1 Fig. 2 is an enlarged section taken on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged end view of a form of my novel fastener;

Fig. 4 is a section taken on the line 4-4 of Fis. 3;

Fig. 5 is a side view of the fastener shown in Figs. 3 and 4; andg a Fig. 6 isan enlarged rear view of a fragment ,0! the installation shown in Fig. 1, including of the cover.

The object of myinvention is to provide a {flexible cover for. theradiators of automobiles may be used in cold weather to prevent. freezing of the cooling liquid and to allow the engine to heat up to proper temperature more rapidly. For some time it has been the practice of automobile manufacturers to provide their cooling systems with thermostats which do not allow the liquid to circulate in the radiator until the engine is warm. Obviously, then, if a motor is started and run in cold weather the danger of freezing the cooling liquid when first starting out is greatly increased, since the water in the radiator is exposed to. I steady stream of cold air. Furthermore, with the advent of-ra diator grilles on the more modern motor vehicles, it is dimcult to attach a cardboard or flexible cover to the grille because the rear side is inaccessible. Therefore the types of fastening members used to attach covers directly to the radiators are not usable, at least not conveniently, as fastening means for radiator grille covers. My invention provides a flexible cover which may be attached to the radiator grille by simple snap fasteners able material such as waterproofed canvas or imitation leather such as is. used in maturehicle tops. Securing this cover. I to the grille 2 one fastener and support, and the adjacent part 1 short distance as shown Divided and this application Novem- Serial No. 109,341. InGreat Britare a plurality of fasteners 3, which are located in apertures in the cover and engage the underlying bars 4 of the grille, as best shown in Figs. 2 and 6. I have also provided a grommet 5 to reinforce the apertures in the cover.-

The radiator grilles forming a part of motor vehicles are formed of spaced rigid bars 4, usually of U-shaped cross section and having spaced parallel flat sides of substantial width.

According to the invention-the fastener may 10 be simple and strong and made from a single piece of spring metal. .This fastener is easily engaged with the grille bars and is slidable thereon by virtue of its-spring grip and its ,flat engaging arms. g by bending a. strip of fiat spring steel or other suitable material in the shape shown in Fig. 4.

It may have a head portion-6 and a pair'of yieldable arms 1 extending from the head and formed The specific form illustrated is formed by bending portions -of the free ends of the strip face of the head for a in Fig. 4. The ends of the strip may be then bent directly away from the head in substantially parallel planes. Towards their ends they each other in gradually increasing curves until they are very close together and then bent sharply away from each other at their extremities. A cap 8 advantageously is attached to the head for the purpose thereof and providing a better appearance and also to make the fastener easier to handle. The sloping shoulders 9 formed by bending the arms as described above are shaped on their sides nearest the head so that they may be used on bars of various cross-sections. The V-shaped opening beyond the points of the shoulders provides a pair of cams which -are adapted to spread the arms when the fastener is being engaged with a bar.

until they lie along one may be bent toward of increasing the rigidity,

. The arms, when formed as described above,

securely grip the flat sides of the supporting bar, yet the fastener may he slid along the bar without removing it from the bar. The grip is strong enough, however, to prevent the cover from slipping out of place of its own accord.

Referring again to the installation as a whole, I prefer to place the apertures in the cover in pairs at opposite sides of the cover near its edge.

Thus the top section may be slid downwards, or

the bottom section maybe moved up towards the top by simply moving the proper pair of fasteners.

The present application is a division of my prior application Serial No. 740,084, filed August 16, 1934.
